A very rare spinal disorder that is identified and diagnosed only by the person who is afflicted. Most often found in hypochondriacs and people who have Munchausen's disorder, even doctors are puzzled by the illness, as the doctor can not find anything wrong with the patient but the patient insists there is an issue.

My cousin says she has a rare disease, eventhough the doctors say there is nothing wrong. Must be spinal perplexia.
